NEWARK — The manager of an IHOP on Bergen Street in the city was killed and two others wounded during an early morning shooting after a dispute erupted inside the restaurant, the Essex County Prosecutor’s Office said.

Papa Khaly Ndiaye, 30, of Middlesex Borough, was pronounced dead at University Hospital several hours after the shooting, said Kathy Carter, a spokeswoman for the prosecutor's office.

One other man remains at University is listed in stable condition. A third man was treated for his injuries and released. Authorities did not say whether those men were employees or customers.

Shots were fired in the restaurant sometime around 3 a.m. following a “disturbance,” authorities said. The three victims were taken to the hospital’s trauma center, across the street from the restaurant.

Authorities released no other details about what might have led to the deadly dispute. No arrests have been made, Carter said in an email.

The homicide is being investigated by the prosecutor's office's homicide/ major crimes task force and city police.

"It was a disturbance inside the IHOP that erupted into a fight between patrons. The manager intervened and shots were fired by one of the persons involved in the fight,” city Police Director Samuel DeMaio said this afternoon. “We have and are interviewing some participants involved in the fight and are downloading and reviewing video from the interior and exterior. The investigation is very fresh and is ongoing."

The IHOP, a popular University Heights restaurant that opened in 2000, is closed today because of the incident — but a sign on the door says employees intend to reopen it on Sunday.

Craig Hoffman, a spokesman for IHOP's corporate offices in California, said he could not comment in detail about the shooting.

“Our franchisee is participating and cooperating fully with the investigation,” Hoffman said.
